PptxGenJS

🚀 Features

PptxGenJS lets you generate professional PowerPoint presentations in JavaScript - directly from Node, React, Vite, Electron, or even the browser. The library outputs standards-compliant Open Office XML (OOXML) files compatible with:

• ✅ Microsoft PowerPoint
• ✅ Apple Keynote
• ✅ LibreOffice Impress
• ✅ Google Slides (via import)

Design custom slides, charts, images, tables, and templates programmatically - no PowerPoint install or license required.

Works Everywhere

• Supports every major modern browser - desktop and mobile
• Seamlessly integrates with Node.js, React, Angular, Vite, and Electron
• Compatible with PowerPoint, Keynote, LibreOffice, and other OOXML apps

Full-Featured

• Create all major slide objects: text, tables, shapes, images, charts, and more
• Define custom Slide Masters for consistent academic or corporate branding
• Supports SVGs, animated GIFs, YouTube embeds, RTL text, and Asian fonts

Simple & Powerful

• Ridiculously easy to use - create a presentation in 4 lines of code
• Full TypeScript definitions for autocomplete and inline documentation
• Includes 75+ demo slides covering every feature and usage pattern

Export Your Way

• Instantly download .pptx files from the browser with proper MIME handling
• Export as base64, Blob, Buffer, or Node stream
• Supports compression and advanced output options for production use

Production-Ready & Type-Safe

This NEOMA-maintained fork (@neoma/pptxgenjs) is hardened for production use:

• Strict null-safety - the entire source compiles under TypeScript strictNullChecks with zero non-null assertions (!) and zero unchecked as casts; null-safety is enforced through honest types, guard clauses, and validated defaults
• Tested in CI - unit, end-to-end, and golden-file OOXML snapshot tests run on Node.js 20 & 22
• Secure - no known vulnerabilities in the published package, CodeQL scanning, and a published security policy
• Requires Node.js 20+ (see CONTRIBUTING.md to build and test locally)

HTML to PowerPoint Magic

• Convert any HTML <table> to one or more slides with a single line of code → Explore the HTML-to-PPTX feature

📖 Documentation

Quick Start Guide

PptxGenJS PowerPoint presentations are created via JavaScript by following 4 basic steps:

Angular/React, ES6, TypeScript

import pptxgen from "@neoma/pptxgenjs";

// 1. Create a new Presentation
let pres = new pptxgen();

// 2. Add a Slide
let slide = pres.addSlide();

// 3. Add one or more objects (Tables, Shapes, Images, Text and Media) to the Slide
let textboxText = "Hello World from PptxGenJS!";
let textboxOpts = { x: 1, y: 1, color: "363636" };
slide.addText(textboxText, textboxOpts);

// 4. Save the Presentation
pres.writeFile();

Script/Web Browser

// 1. Create a new Presentation
let pres = new PptxGenJS();

// 2. Add a Slide
let slide = pres.addSlide();

// 3. Add one or more objects (Tables, Shapes, Images, Text and Media) to the Slide
let textboxText = "Hello World from PptxGenJS!";
let textboxOpts = { x: 1, y: 1, color: "363636" };
slide.addText(textboxText, textboxOpts);

// 4. Save the Presentation
pres.writeFile();

That's really all there is to it!
